J.J. Harwood, S. R. Koirtyohann, C.J. Schmitt
1987, Water, Air, & Soil Pollution (34) 31-43
Five raised-bed test plots were used to study the effects of cover materials on the leaching of constituents from dolomitic Pb mine tailings over a 2-yr period. The cover materials studied were a fertilizer and seed mixture, anaerobically digested sewage sludge, loam and sod, and fallen leaves from silver maples...
Ground-water contamination near a uranium tailings disposal site in Colorado
Daniel J. Goode, Russell J. Wilder
1987, Ground Water (25) 545-554
Contaminants from uranium tailings disposed of at an active mill in Colorado have seeped into the shallow ground water onsite. This ground water discharges into the Arkansas River Valley through a superposed stream channel cut in the resistant sandstone ridge at the edge of a synclinal basin. In the river...

Michael K. Saiki, T. Peter Lowe
1987, Archives of Environmental Contamination and Toxicology (16) 657-670
Concentrations of total selenium were high in 1983 in water, sediment, organic detritus, aquatic plants and invertebrates, and mosquitofish (Gambusia affinis) from Kesterson Reservoir (San Joaquin Valley, California) and the San Luis Drain. Selenium concentrations in biota from the Reservoir and Drain (referred to here collectively as “Kesterson”)...
Laboratory investigation of longitudinal dispersion in anisotropic porous media
Stephen E. Silliman, Leonard F. Konikow, C.I. Voss
1987, Water Resources Research (23) 2145-2151
In this study, laboratory experiments were used to investigate mechanisms that may cause anisotropy in the dispersion coefficient and to investigate the relation between anisotropy in hydraulic conductivity and anisotropy in longitudinal dispersion. Measurements of sodium chloride concentration (used as a tracer) were made at 105 in situ sampling locations...
Toxicity of TFM lampricide to early life stages of walleye
J.G. Seelye
1987, North American Journal of Fisheries Management (7) 598-601
We studied the effects of the lampricide 3-trifluoromethyl-4-nitrophenol (TFM) on gametes, newly fertilized eggs, eyed eggs, larvae, and swim-up fry of the walleye Stizostedion vitreum. When gametes from sexually mature walleyes were stripped into solutions of TFM, no effects were observed during the fertilization process at concentrations up to 3.0...
Minimum tailwater flows in relation to habitat suitability and sport-fish harvest
K.E. Jacobs, W.D. Swink, J.F. Novotny
1987, North American Journal of Fisheries Management (7) 569-574
The instream flow needs of four sport fishes (rainbow trout Salmo gairdneri, channel catfish Ictalurus punctatus, smallmouth bass Micropterus dolomieui, and white crappie Pomoxis annularis) were evaluated in the tailwater below Green River Lake, Kentucky. The Newcombe method, a simple procedure developed in British Columbia that is based on the...
Selective transport of hydrocarbons in the unsaturated zone due to aqueous and vapor phase partitioning
Arthur L. Baehr
1987, Water Resources Research (23) 1926-1938
Long-term groundwater contamination can result from vapors and solutes emanating from organic liquids spilled in the unsaturated zone. The mathematical modeling analysis presented in this paper demonstrates for gasoline-range hydrocarbons, and other volatile organics commonly spilled, that diffusive transport in the unsaturated zone is a significant transport mechanism which can...
Contributions of rainfall to constituent loads in storm runoff from urban catchments
J.C. Ebbert, R. J. Wagner
1987, Journal of the American Water Resources Association (23) 867-871
Rainfall is a significant source of some constituents, particularly nitrogen species, in storm runoff from urban catchments. Median contributions of rainfall to storm runoff loads of 12 constituents from 31 urban catchments, representing eight geographic locations within the United States, ranged from 2 percent for suspended solids to 74 percent...
Examples of landfill-generated plumes in low-relief areas, southeast Florida
Gary M. Russell, Mark Stewart, Aaron L. Higer
1987, Journal of the American Water Resources Association (23) 863-866
Areas of low topographic relief have low water-table gradients and make the direction of movement of contaminants from land fills in the ground water difficult to predict from regional gradients alone. The landfill, nearby free-flowing ditches or canals, variations in hydraulic conductivity, and the influence of nearby pumping wells can...

Movement and fate of crude-oil in contaminants in the subsurface environment at Bemidji, Minnesota: Chapter C in U.S. Geological Survey program on toxic waste--ground-water contamination: Proceedings of the Third technical meeting, Pensacola, Florida, March 23-27, 1987
Marc F. Hult
1987, Open-File Report 87-109-C
On August 20, 1979, a pipeline break in a remote area near Bemidji, Minn. (fig. C-l), resulted in the release of 1.5x105 L (liters) of crude oil. Although about 1.1x105 L were removed from the site as part of the cleanup, some crude oil infiltrated the ground and percolated to the...
